To aZZ 'who me't may concern;

Be itknown that I,-' a

citizen of the United'S tat'es, residingii a lentown, Lehigh county,{Pennsylvan1a, have invented certain new'and' useful Improvements .in Dumping Mechanism for Motor clear, and exact specification.

This invention relatesifto motorivehicles of the type which are provided withtilting 1 body portions. 1

One of the objects of theinvention is to provide means for raising and lowering a body portion by means of the motor which 0 operates the vehicle.

matically disconnecting the 'motorj -from the ,body actuatingmeans after the body has i been raised the desired distance and as the body returns to its normal position; i Another object. is to provide means. for positively preventing the body actuating means from being actuated by any of the -i speed gears of the transmission mechanism except the low speed gear and the reverse gear. I

Upon the opposite. ends of the shaft are fixed sprocket wheels 77, 7 7 ,o-ver which'pa'ss Upon the rear Wall of the cabin l5 adjacent-to its top are provlded at each. side thereof rearwardly ex-, tending'brackets 76 76 ,.in which is sup- 75 denotes a transverse shaft which is ported a shaft. 75*, having fixed thereon sprocket ,wheels 77*, 77, over which the sprocket-chains 77",. 7 7 also extend.

ranged projecting lugs or pins 79, 79,

which are; adapted to contact respectively with' the lower and upper edges of a box 107 is provided with a projection 108 to which is fixed the upper end of a rod 106. The

{which surrounds said chain 77 and which is fixedupon a short transverse shaft 109;

Upon this shaft is fixed a stop 10 1 compris- 'ing a pair of forwardly extending. members 105?, 105". Upon the. inner end of the shaft 109 is loosely mounted a bell crank lever 110, having a horizontalmember 110 and a depending verticalmember 110". The forward end of the horizontal member 110 of thefbell' crank-lever 110 is pivotallysewhich is provided witha curved face '111 conformed to th'e ends ofthe stops 105*. The forward end of the link 111 is In front of and slightly above'the short shaft 109 is mounted a transverse shaft79, having an operating lever 82 secured to one end. thereof and adjacent to its other end is secured an upwardly extendingarm 80 conpivotally connected to the rear side of the 'clutcheoperating lever. 112. 10,0

nec'ted by the link 81 with the lever 55 secured to the upper projecting end ofthe vertical shaft 51, which extends through the transmission casing 11. i

113 denotes a short forwardly extending arm fixed upon the shaft 19 intermediate its ends, and having pivotally secured at its 'iuter end the upper end of a. link 115, which has its lower end pivotally secured to a lock transverse shaft 116. Upon this sleeve is fixed the upper end of a depending arm 117" the lower end of which is pivotally connected to a link 21 which is connected to the forward end of the tubular shifting rod 21.

Secured to theshaft 116 is the upper end of a depending arm 117 the lower end of which is pivotally connected to a link 31) which is connected to the forward end of the solid shifting rod 31 working within the tubular rod' 21. v

Arranged upon and surrounding the for- V ward end of the shaft 90, between the longitudinal frame member 10 and the longitudinal sub-frame member 10,.1s a sleeve 90", UPOItWlllCll 1s fixed a depending arm 120,

a which is pivotally connected at its lower end by means of a link 119, to a lower end of an arm 118, which is fixed upon the shaft 116.

The link 119 with the arms 11S and 120 serves to connect the sleeve 90 with the vshaft 116, arm 117*, link 31 and shifting rod 31, in order to operate the second and high speed gears.

Adjacent to the inner side of the arm 120 is arranged an arm 120, which is fixedupon the forward end of the sleeve 90*, surrounding the shaft 90 and working within the sleeve 90.". The lower end of the arm 120 is 'pivotally connected, bymeans of a link 119,

to the lower end of an arm 118 fixed upon the forward end of the sleeve 116? surrounding the shaft 116. The link 119 and arms 120 and 11S serve to connect the sleeve 90 with the sleeve 116, arm 117 and link 21 with the tubular shifting rod 21 of the transmission, in order to operate the first speed gear and the reverse gear.

Upon the sleeve 90, intermediate the subframe members 10, 10*, are fixed two up- Wardlyextending arms 121, 121, the upper ends of which are pivotally secured to the rear ends of links 122, 122, which are connected at their forward ends to the clutch collar 13 loosely mounted on the clutch 13.

The clutch 13 is operated by means of the clutch pedal 112, fixed upon the forward end of the sleeve 90.

The tilting body portion 16 is prov ded at its sides adjacent to its forward end wlth depending arms 1023, 103, to which links 100, 100 are connected, which links have their other ends connected to the chains 77, 7 7

The operation of the device is as follows; it being assumed that the parts are in their neutral or normal positions and the car at rest. It merely becomes necessary to push the upper end of the lever 82- forwardly and downwardly, thereby covering the upper end of the supplemental lever 123", and the slot in the segmental plate within which it works in order to control the second and high speeds, This will prevent the transmission lever 123 engaging the said supplemental lever and will lock the same against accidental connection therewith. By lowering the lever 82, the link 81 is drawn forward and the lever 55 of the transmission mechanism moved in the same direction, thereby partially rotating the vertical shaft 51 in the transmission casing 11, and placing in commission the hoisting mechanism comprising the extra shaft 50, worm 7S, worm gear 78, shaft 75, and the chain operated mechanism which is arranged upon the rear of the cabin 1:3. The means whereby the extra shaft 50 is placed in commission is fully explained in my co-pending applica tion, Serial Number 726,028, filed October 16, 1912. Vith the same operation of the lever 82, the link 115 is forced downwardly which causes the recessed forward end of the locking lever 111 to be released from the sleeve 90, surrounding the shaft 90, and at the same time causes the recess 111 to engage the projecting pin 11%", arranged upon the depending lever 117, and to hold the a parts to the neutral position. This serves to connect the link 21? with the lever 11-1, by

means of the pin 111", whereupon .the parts movejointly. In order now to elevate the forward end of the vehicle body 16 it becomes necessary to apply the power, which may be done by moving the transmission lever 123 outwardly and causing the same to lock with the supplemental lever 123 on the outer end of the shaft 90, thereby operating the first speed of the transmission. this being effected through the medium of the arm 120, on the sleeve 90. link 119, arm 118 on the sleeve 116, and thereby partia ly rotating said sleeve 116, arms 117 117 link 21", and the tubular shifting'rod 21 which is thereby forced rearwardly or inwardly into the casing and the first speed clutch thrown into operation. As the recess 11-1 of the locking lever 111 is in engagement with the pin 111", the said locking lever is moved bodily to the rear and thereby causes the vertical member 110 of the bell crank lever 110 to be. forced rearwardly and the horizontal member 110 towardly to its lowermost position so that its curved; end 111* shall 'be opposite to and izbe I box to descend, and in so doing 'depressthe lever 105 and partlyrotatefthe shaft- 109.

- This will cause the stop 105?,to-"engage'the" curved end 111 upon: the inner} end of the arm 111, force the same l'forwardly. together-1 with the clutch pedal 112,; and thereliy dis conneot the clutch from the fiy e'e1;-1oa1 e e.
